For saltwater fly fishing you need a minimum 8 wt outit. A 10 wt is more appropriate.
You are casting bigger/heavier flies, and most times you have to deal with the wind.
Saltwater fly lines are also different from freshwater lines.
If you are planning to get saltwater lines for use in India, suggest you get saltwater flylines with a tropical coating.
On a very calm day, you can get away with a 6 wt outfit.
Also the 5 wt you have looks made for freshwater.
Thanks for the info. I am about to get my 9wt saltwater fly gear, but there are a lot of freshwater fishing close by, so I also thought of making use of the oppertunity. The 5 wt rod in the above pic is an Orvis TLS Power Matrix rod and the reel is an Orvis Battenkill Mid Arbour III reel. I thought of using this setup for very light saltwater fish, considering that this gear will stand up to corrosion if rinsed with freshwater and taken care after use.
BTW, I had a blast in the stream today and here is a pic I took of a smallmouth bass. For the size, they put up a great fight.
